Every player picked in the NFL Draft receives a four-year contract. Each contract of a first-round pick also includes a fifth-year team option.

The Rams selected Robinson out of Auburn with the second pick in the 2014 NFL Draft. The deadline for exercising the option for first-round picks in the 2014 NFL Draft is Wednesday.

Robinson is one of the nine first-round picks from 2014 that won't have their options picked up. Three of the players are no longer with their teams. Twenty-three of the remaining 29 first-round picks have had their options exercised.

For a player picked in Robinson's spot and position in the draft, the value of his fifth-year option is the average salary of the 10 highest-paid offensive linemen. Robinson's option was projected to be worth $12,496,000 for the 2018 season.

The Rams' decision means Robinson will become a free agent after the 2017 season unless Los Angeles reaches a contract extension with him before the start of the NFL's 2018 business year in March.

Robinson became the Rams' starting left offensive tackle during his rookie season and had held that spot the previous two years. But in March, the Rams signed veteran left tackle Andrew Whitworth from the Cincinnati Bengals in free agency and indicated Robinson would be moved to right tackle for the 2017 season.

The Rams, then in St. Louis, selected Auburn's left offensive tackle with the intent of making him their left guard to open his career. He hardly played in the first four games of the season, then started three games at left guard.

When left tackle Jake Long suffered a season-ending knee injury in the seventh game, Robinson shifted to the opening and started the final nine games of the season at left tackle.

In his second season, Robinson played all but one of the St. Louis Rams' 961 offensive snaps at left offensive tackle in 2015.

Robinson played every snap at left offensive tackle for the Rams in 2016, except for two games when he was benched.
